塵
チン, ジン, ちり, ごみ

dust, trash, garbage

JLPT0 G13 S0 F5000

鹿 (long herd of) deer + 土 earth → *dust* kicked up by an advancing herd of deer → *dirt* → *trash*; *waste*. As the Old Chinese pronunciation of 塵 matches that of 廛 (long strip), the two characters are graphically similar, and both involve long strings of objects, 塵 may be regarded as a variant and reinterpreted form of 廛.
